带有USB接口的井下数据采集与存储系统

Oil well data acquisition and store system with USB interface

本文介绍了基于Cygnal公司的带有USB接口的C8051F320单片机设计的井下数据采集电路。此电路模块可随探头深入井下,就地采集和存储数据;在探头返回地面以后,又可通过USB接口向PC回放数据。该采集系统具有体积小、功耗低和数据回放速度高的特点,并能满足在井下高温高压的工业环境中长时间工作的要求。

This paper introduces an oil well data acquisition circuit based on C8051F320 SOC with USB interface. The circuit module acquires and stores data in deep oil well, and returns data to PC through its USB interface above ground. Small, low power and highly data-returned speed are the acquisition system's characteristics, it accords with the request of working in deep oil well for long time under industrial condition including high temperature and high-handed.
